**OFFICIAL Gigabyte UD3 P45 Yorkfield (45nm Quads) OC and Discussion Thread**

[Elektrosadist]

heres some watercooling Pics from me and my current system settings. FSB 505 along with DDR2-1263 with relaxed timings works fine here. I found Bios F4 to be the most stable and clockable with Quad and this Board. F5A caused BSOD for me. The CPU i have was pretested in a shop with FSB 471 @ 4G on air and i pumped it a little more. I also chatted a long while with the shop owner there and he said he also tested the F4, f4PI and the F5A Bios and the most reliable for Quads is the F4. I will later make a SS with ET6. And i don't know how extend you guys test, i do Prime for like 6h OCCT for 3h as well as 20 runs of the INTELBURNTEST and then i run all synthetic benchmarks i have (3dmark and pcmark stuff, superpi, everest, sandra and some more). After all that is passed i just use the system (surfing gaming benching a lil)and when i dont get a blue screen for some weeks i refeer to this as stable. I just say this cause i know some of you do Prime for days.
